and exact description.

My invention relates to attachments for supplying paper from acontinuous roll or rolls to the platen oftypewriting machines, addingmachines,and the like. I am aware that this has been done before, and Iam also aware that some of the attachments for accomplishing this resultuse. devices for the-purpose of feedingthe paper at rightangles to theplaten and keeping the same in register. Experience has shown that insome instances these devlces resist the effort to rotate the platen onits own axis or resist the reciprocable movement of the carriage of themachine in which the platen is journaled, and cannot be relied upon, insome instances with certainty, to feed the paper at right angles to theplaten and always in register with each other. The consequence of thesedefects is, particularly when manifold copies are being made, to causethe print on the manifold copies to get out of place, or register, andoftentimes results in confusion that destroys the value of the manifoldwork as correct copies.

The principal object of my invention is to feed paper from one or morerolls having relatively stationary bearings, to the platen journaled inthe transversely reciprocable carriage of a typewriting machine, or therotatable platen of an adding machine, without twisting the paperstripsto such an extent as to resist the movement of the carriage or getthe said strips out of register with one another. I

It is also an object of my invention to provide means for directing themovement of the paper strips to the platen at rightangles to the axis,thereof, and it is a further object to rotate the rollssimultaneouslywith and to the same extent as the platen, so that theintermittent forward movement of the said strips will be the same inevery instance regardless of the diameter or diameters of the roll orrolls.

These and other objects I accomplish by the means hereinafter fullydescribed, and

.as particularly pointed out in the claims.

In the drawings: Figure 1 is a side elevation of a typewriting machinehaving my improvements applied thereto and the stationary rolls of paperstrips, and support therefor, partially broken away to illustrate theoperation of said improvements. F 1g. 2 1s a top plan view of the same.Fig. 3 is a fragmentary side elevation of a sl ghtly modified form of myinvention. Fig. 4: is a diagrammatic View ofthe loop of paper betweenthe rolls and the platen and illustrating the twist of the samein two p0sitions of the typewriter carriage.

For the purpose of convenience. I have herein illustrated and describedmy improvements applied. to a standard typewriting machine of thevisible type, but my improvements are equally applicable to other makesof typewriters of the nonvisilo'le type, as well as to adding andbilling machines, and to combined typewriting and adding machines of theusual design, or to book-typewriters wherein the platen is a flatstationary plate over which the writing mechanism is moved.

My invention, as shown in the drawings, comprises, in combination, atypewriting machine A, a table or desk B upon which sald machine ismounted, and a rack or frame for journaling one or more rolls of paperstrips, together with mechanism. for connecting and accomplishing thecoeperation of these three principal elements.

The typewriting machine may be of any of the standard construction, asabove mentioned, having a revoluble platen 2 journaled 1n a transverselyreciprocable carriage 3, and the table or support for this machine maybe of any suitable construction having.

a false top 4 that extends a considerable distance to the rear sidethereof and is prov1ded with a transverse slot 5 therein a suitabledistance back of the rear of the desk.

The frame for journaling the rolls of paper strips or records? to beused in the typewr ting machine, comprises two vertical uprights 6, 6,arising from the rear extension ofthe top of the desk just back of theslot 5 therein, and suitably braced by braces 7, These frames areseparated. a suitable distance apart and are provided with forwardlyprojecting lugs 8, 8, 'in which the journals of the rollers 9 upon whichthe record-rolls 10 are wound.

In Fig. 1 of the drawings, five of these record-rolls are shown to bejournaled, one

above the other, in uprights 6, 6, and the record strips are drawndownward therefrom in the same vertical plane through slot 5 in the rearextension of the top of the desk to a point very near the floor and thensaid record strips are extended vertically up throughsaid slot 5 to apoint slightly above the plane of the typewriting machine where they arepassed between guide-rollers 11, 11, and their coursechanged in ahorizontal direction to a series of idle-rollers 12, 12, that separateeach record from the others and direct them in a downward direction toand under the platen of the typewriting machine, for the convenientengagement of the typ Guide-rollers, 11, 11, are secured in uprightframes or posts 13 secured to and arising from the rear ends of theextensions or bars 14, 11, the forward portions of which latter arescrewed or otherwise attached to the side-frames 15, 15, of the carriage3.

Idle-rollers 12, 12, are journaled in standards 16 secured to' andarising from said bars 1 1 at the rear of the carriage.

The principal feature of my invention is the stretch of slack recordstrips between the feed 7 rolls and the typewriting machine. Themaintenance of this slack during the operation of the typewritingmachine is essential. In order to accomplish this it is necessary toprovide means for transmitting the rotary movement of the platen to therolls of paper, and to do this without said transmission means beingaffected by the longitudinal movement of the carriage. Said meanscomprise a shaft 17 whose axis is horizontal and parallel to the axis ofthe platen and which is located to the rear of the typewriting machineunder the rear extension of the bars 14. Said shaft is journaled insuitable standards 18, 18, secured to and arising from the top of thedesk upon which the typewriting machine is supported,

and these standards are located a suflicient distance apart to permit ofthe longitudinal movement of the carriage.

Shaft 17 is provided with a longitudinal groove 19, and a sprocket-wheel20 is mounted thereon that has a tenon projecting inward from itscentral opening into the groove 19 so as to permit the sprocket to movelongitudinally on said shaft, but be rotatable therewith. Sprocket 20 isprovided with an integral disk 21 on the side thereof adjacent to one ofthe bars 14, and this disk has a circumferential groove in itsperiphery, and this groove is engaged by v a finger 22 the shank ofwhichis secured,

preferably, to the extension of the left-hand bar 14, thus, as thecarrier of the machine reciprocates longitudinall it causes the sprocket20 to move longitudinally on the shaft 17 simultaneously therewith.

One end, preferably, the left-hand end, of

the journal 23 of the platen has a milled hand-wheel (heretofore usedfor rotating the platen) removed, and a sprocket 24- securely mountedthereon which is connected by means of an endless chain 25 to thesprocket 20. These sprockets are of the same diameter, and thus when theplaten is rotated shaft 17 will rotate simultaneously therewith and to acorresponding extent.

The left hand end of shaft 17 extends through its bearings and has asprocket 26 mounted on the same, and this sprocket is connected by meansof a suitable chain belt 27 to a sprocket 28 securely mounted on theadjacent end of a horizontal shaft 29 the ends of which are journaled insuitable bearings or hangers 30 secured to the underside of theextension of the top of the desk.

Shaft 29 is disposed-in a vertical plane between the longitudinal edgesof the slot 5, and about'midway of its bearings it is provided withafriction roller 31. The record-strips just below the slot'5 are engagedby this roller31 and a corresponding idle-roller 32, the shaft of whichis arranged parallel therewith, and is journaled in suitable hangers 33secured to the underside of the top 4 immediately to the rear of slot 5.These rollers 31 and 32 engage the recordstfips and through the mediumof sprocket and chain mechanism, hereinbefore described, rotate.simultaneously and to the same extent as the platen, and draw the recordstrips downward from the rollers 10 and maintain the slack of therecordstrips below the rear extension of the top of the desk all thetime.

"If desired, the-slack of therecord-strips below the extension of thetop of the desk may be inclosed by a suitable casing 34. The stretch 'ofthe record-strips hanging down from the guide-rollers 11 extends inasubstantially vertical plane to the bend of the slack portion thereof,and when the carriage of the machine reciprocates, assumes a slightincline in the one direction or the other, according to the movements ofthe carriage, but does not wrinkle or pucker, owing to the ability ofthe bend of the slack to tilt or twist in one direction or the other.This feature constitutes the principal improvement in this class ofattachments,.and while this may be accomplished by other mechanism, Iprefer to employ that hereinbefore described.

Suitable manifolding ribbon mechanism, such as are used in other devicesof this character, are employed in order that the typewritten matter onthe original sheet may be simultaneously written upon the man foldcopies or record sheets. vices, as shown and described in prior LettersPatents of the United States, Numbers 812,177 and 870,336, granted to meFebruary 13, 1906 and November 5, 1907 ,'respectivelv.

Such deare preferred, but of course it is understood that any well-knownand adaptable mechanism may be employed for this purpose, and

I, therefore, do not deem it necessary toherein specifically describethe same.

In the modification disclosed in Fig. 3 of the drawings all the partsare substantially the same as in the form aboveIdescribed, except thatinstead of mountingthe parallel extensions 14' directly upon thecarriage of the typewriter, a suitable frame X is substituted thereforthat is mounted upon and carried by shaft 17, as shown. This frame X isadapted to be moved through the me dium of and longitudinally andparallel with the typewriter carriage 3 by means of suitable arms Y thatare secured to-the sideframes 15 of said carriage and project to therear thereof, or by other suitable devices.

In order to assist in registering or alining the record strips after thesame' have been threaded into the typewriter, especially when two ormore record. rolls are employed,

I prefer to divide or. separate said strips, in their passage betweenguide 11 and the idle-rollers 12, by several transversely. disposedhorizontal rods or rollers w, a, so that when the operator desires toadjust these record strips he holds the registered strips by clampingeach betweenone of his fingers and the respective dividing rod andthereafter draws or pulls the remaining strip or strips under or pastthe platen until the same are in proper register with the others. Afterthe record strips leave the platen they pass under a suitablecutter-blade andare adapted to be torn off in the desired lengths. Forconvenience in feedingthe paper strips and for rotating the platen, Iprefer to mount a milled hand-wheel on the righthand extended portion ofshaft 17 so that by turning the same the platen will be ro-- tated bychain 25-- and the feed rollers 31 chine of the kind specified having aplaten,

and 32 will be actuated through the medium of chain 27.
